I was going through some of my pgaes today with Web CEO and came across the following code:
This is before the <head> tag
<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns="urn:schemas-microsoft-comfficeffice" xmlns="http://www.w3.org/TR/REC-html40">

This is just before the </head. tag
<!--[if !mso]>
<style>
v\:* { behavior: url(#default#VML) }
o\:* { behavior: url(#default#VML) }
.shape { behavior: url(#default#VML) }
</style>
<![endif]--><!--[if gte mso 9]>
<xml><o:shapedefaults v:ext="edit" spidmax="1027"/>
</xml><![endif]-->

It's commented out but what does it do? Im a novice making a website during his spare time at work for the boss, and I suspect it's some rubbish that Frontpage has generated but Ive not seen it on any other pages.

Thoughts?
